Indicated position recognizing apparatus and information input apparatus having same

An image displaying apparatus comprising:

• a scanning device that two-dimensionally scans invisible light on a surface to be scanned;
• an indicating device that indicates at least one position on the surface to be scanned;
• a light receiving device that receives invisible light deflected by the indicating device, wherein a light receiving timing of the received invisible light is obtained;
• a drawing-light-beam projecting unit that projects a visible drawing light beam modulated on the basis of image information onto the surface to be scanned;
• and
• a position detecting device that obtains the position indicated by the indicating device in an image projected by the drawing-light-beam projecting unit, on the basis of the light receiving timing.

An image displaying apparatus comprising:

• a drawing-light-beam projecting unit that projects an image onto a surface to be scanned using a visible drawing light beam modulated on the basis of image information;
• a scanning device that two-dimensionally scans invisible light on the surface to be scanned;
• an indicating device that indicates at least one position on the surface to be scanned;
• and
• a light receiving device that receives invisible light deflected by the indicating device, wherein a light receiving timing of the received invisible light is obtained,
• wherein a predetermined image is displayed at the position indicated by the indicating device in the surface to be scanned, by modulating the drawing light beam corresponding to the position indicated by the indicating device, on the basis of the light receiving timing.

An image displaying apparatus comprising:

• a drawing-light-beam projecting unit that projects a visible drawing light beam modulated on the basis of image information;
• a scanning device that two-dimensionally scans visible light emitted from the drawing-light-beam projecting unit and invisible light on a surface to be scanned;
• an indicating device that indicates at least one position on the surface to be scanned;
• and
• a light receiving device that receives invisible light deflected by the indicating device, wherein a light receiving timing of the received invisible light is obtained;
• and
• a position detecting device that obtains the position indicated by the indicating device in an image projected by the drawing-light-beam projecting unit, on the basis of the light receiving timing.
